I'm interested in making a 125" wheelbase Blazer with reg cab and flat deck.
Why not just get a burb frame and put a cab on it?
Why 125, precisely?
I would think a shortbed (stock wheelbase 117.5") with 56"s in the back and 52"s up front would be right about where you wanna be, and already be set up for the cab/bed. Or you could use a Burb frame (stock WB 129.5") or a longbed (131.5").
I want to use a 92 Dakota cab and box because I have one sitting here in the yard with a rolled 74 Blazer that runs and drives great.
Then I would look for a frame donor from a shortbed truck and use 3 trucks to make one. Isn't a blazer 109" wheel base? I'm not sure you could add 16" of wheel base in any practical manner.
Running 56s in the rear rotated 180° + zero rate you could gain 5.5"
Running 52s in the front + zero rate you could gain 3.5"
I suppose you could move spring hangers. You'd want to do that in the rear, not much more room in the front after 52s. I'm sure there's another 7" you'd could gain in the rear moving the hangers back further. However you'd run into problems with the front hanger moving into the area where the frame curves up over the rear axle. That might get tricky.
That sounds like WAY too much work...
It would be a lot of work to stretch one that long, with leaf springs. I would guess you could get to around 116 to 118 with out stretching the frame.
If you linked the rear suspension, you could make it as long as you want.
I'm also wondering why you want 125" of wheelbase. I also think that it would be easier to start with a longer frame, either a shortbed or swaping the blazer drivetrain into the dakota (if it already is close to 125)
Thanks for the input guys. I'm just looking to get a 3/4 ton chassis under my dakota and hopefully end up with a GM motor. The reg cab short box is too short but closer to what I want so I'll look into that.
I know of some people who have shortened frames to work with other bodies but havent heard of lengthening it. I am certain it could be done though as I have seen some crazy stretched limo ideas. As long as the frame was strengthened appropriately at the stretch area then i cant imagine it would be a problem, just lots of work getting the frame square.
bob the 'kota bed and just run a 52/56 combo on the blazer chassis.
install the dakota cab, and then modify/bob the bed to fit. SOunds alot easier than stretching the frame,driveshafts,brake lines,electrical,exhaust, and gas lines.
